METHOD OF MANUFACTURING AUTOMOBILE RADIATORS.

Application filed May 30,

To all whom it may concern Be it known that 1, WILLIAM Koran, a citizen of the United States, residing at Cheviot, in the county of Hamilton and State of Ohio, have invented certain new and useful Methods of llfanufacturing Automobile Radiators, of which. the following is a specification.

My invention relates to' radiator cores particularly adapted for use in cooling water adapted to lower the temperature of internal combustion engines. I

Heretofore it has been the practice among manufacturers of automobile radiator cores to form two sheets of metal, one different from the other; the o 19 being adapted to be inserted between the other sheet, after being cut and seamed together, whereby a section is formed for the purpose of con'iprising a plurality of tubes adapted when combined with other sections to provide admittance of water between said sections and over said tubes.

The objects of my invention are to provide means adapted to simplify the construction of-radiator cores; to provide means adapted to affect a great saving in material; to provide means for constructing a radiator core from a plurality of pieces of sheet metal each being formed similar to the other, whereby the use of but one form of die is required, thereby greatly reducing the costof manufacturing said core; to provide a simple, efficient, economical and practical radiator core having adaptability to be constructed from a plurality of similar pieces offormed sheet metal and which operations being successively performed considerably reduce the usual time required in manufacturing a radiator core; and to provide a radiator core having adaptability to perform efficient service and having similar appearance to radiators heretofore manufactured.

My invention consists in forming a plurality of pieces of sheet material similar to one another, so that when each piece is bent upon itself a plurality of times, 'a section'is formed which when combined with a plurality of other similar sections, a radiator core is formed having a space between adjacent sections adapted to permit the flow of water therethrough and over the walls of the sections each having an air space therebetween, whereby the temperature of said water is adapted to be lowered.

My invention further consists in the de 1924. Serial No. 716,840.

tails of construction, combination, arrangement and location of parts, as herein set forth and claimed.

In the drawing:

Fig. 1 is a perspective view of my radiator core showing a portion thereof broken away;

Fig. 2 is a vertical section showing two sections of my radiator core, and broken away;

Fig. 3 is a perspective view of my formed metal sheet; and

Fig. l is a front elevation of the same after successive operations are performed.

In the preferred construction of my invention I provide metal sheet 1 stamped, pressed and formed by suitable means to a form shown in Fig. 3 with the longitudinal edges 2 and 3 or 2 and 3' bent at right angles to body 4. Longitudinal edge 3 may be extended to the position shown in Fig. 3 when it is desired to provide a full size button at the top and bottom of the radiator core, as will be hereinafter explained. Integral with the sheet and intermediate edges 2 and 3 are a plurality of equi-distance spaced apart. and transversely and longitudinally alined tongues 5 extending outwardly in parallel relation to edges 2 and 3. The tongues are formed from a portion of the sheet thereby providing perforations 6 adjacent each tongue. The tongues are arranged in groups 7 and 8, respectively, having notches 9 and 10 formed in body 4 adjacent the respective outer tongues 11 and 12 of the two groups. Group 7 is adjacent transverse edge 13 of body 4 and separated therefrom by angular strip 14 having 60 angular portion 15 adjacent each perforation between the tongues. Angular portions 15 have apexes 16, respectively, adjacent the transverse center portion of perforations 6 and apexes 17, respectively. adjacent outer edges 18 of the tongues. Group 8 of tongues 5 is intermediate and extends parallel to transverse edges 13 and 19 of body 4 and extends parallel also to group 7.

Angular strips 20 and 21, respectively, are adjacent group 8 of tongues 5 and disposed on either side thereof and extend parallel thereto. The angular strips 20 and Ql each comprise 60 angular portion 22 somewhat wider but of similar formation to angular portions 15' of strip 14. Angular portions 22, respectively, have apexes 23 and 24;, respectively, in alinement with apenes 16 and 17 of strip 141-.

Angular strip adjacent transverse CII edge 19 of body 1 also is composed of angular portions 22, respectively, in alinement with angular portions 22 of angular strips 20 and 21., respectively. Adjacent the inner edge 26 of group 7 of tongues is angulai strip 27 having angular portions 22, respectively, in alinement with angular portions 22 in strips 20, 21 and 25.

Intermediate angular strips 20 and 27 and 21 and 25, respectively, are transverse strips 28 and 29 having curved depressions 30.

The sheet 1, as shown in Fig. 3, may be formed by suitable means after which strip 1% is bent with apexes 17 of angular portion in engagement with outer edges 31 of tongues 5 in group 7. The tongues 5 in group 7 are then bent with inner edges 26, respectively, in engagement with apexes 3:2 of angular strip 27. The angular strip is then bent with apexes 24; respectively in on gagement with edges 33 of tongues 5 in group S. The tongues 5 in group 8 are then bent with edges 3%, respectively, in engagement with apexes 2t of angular portions 21. The angular strip is then bent with apexes 23 and 2st, respectively, in engagement with apexes 16 and 17 of angular strip lei and overlapping edges 2 and 3, respectively, are soldered, whereby a section of my radiator core is formed and ready for assemblage with other sectionsfor the pur pose of forming a radiator core 36.

In Fig. 1 two sections35 are shown in as sembled position whereby water space 37 is formed at the top thereof thereby permitting the entrance of water therein. The water is adapted to drain downwardly over walls 38 of the adjacent sections, thereby being cooled by currents of air passing; through air spaces 39. The outer ends e0 of the sections are secured together by suitable means, as by dipping in a bath of solder, thereby securing the sections together and sealing the ends of water spaces 37.

Longitudinal edge 3 may be extendedto 3, asshown in 3, whereby a full size button or cell 11 is formed the top and bottom, respectively, of each section 35;

An advantage of my invention is that for the purpose of manufacturing my radiator core I merely provide myself with a plurality of flat pieces of metal, all of which may be formed by the use of the same die and press, thereby eliminating the expense occasioned by the investment of various types of dies, as well as considerably affecting the advantageous features of my invention from the standpoint of reduced labor and material costs compared with the usual method of manufacturing radiator cores. Although I have devised means by which a radiator core may be quickly, eificiently and economically manufactured, I have also provided a construction which is adapted to perform the functions intended with great efficiency and with little likelihood of the core itself requiring repairs or other attention due to the vibrations and shocks which it may receive.

It is. apparent that I have invented a sun- )le efficient and aractical radiator core whereby it is not necessary to employ the use of various pieces of machinery for press ing the same and that it is not necessary to carry an overly large st ck of material inasmuch as my complete core is manufactured from similar pieces of flat sheet material.

While I have chosen to illustrate the form of construction of my invention by the llOl'( in drawings and explanation of the same, I desire to emphasize the fact that the form and the explanation as relates thereto, are not intended to include the various forms of modification, in which my invention may be incorporated. It is understood that my invention resides in the combination, arrangement of parts and the details of construction, as hereinafter claimed, and that changes in the precise embodiment of the invention as herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.
